The object of my invention is the production of a glue to be used in the manufacture Qf wooden articles, such as columns, doors and furniture, which is water resistant, of great strength, does not excessively wear the knives of the machinery working on the wood, and which is considerably cheaper than other glues of corresponding characteristics.

One of the major problems in the manufacture of wooden articles from glued stock, such as veneer construction, is the fact that when the rapidly moving knives of the machine pass over a glued joint the knives wear away very much more rapidly at the point of contact with the glue than at any other point of their length and that therefore they have to be removed from the machine much more often in order to maintain the desired uniformity of quality of work produced. This difliculty is successfully solved by my glue, which also has all the other desirable qualities of other glues.

My composition consists of a mixture of pegn ut meal, commercial borax, caustic soda, permanganate of potash, hydrated lime, and copper sulphate, and the addition of calcium chloride and sodium silicate thereto.

acts as a filler.

In preparing the glue for use the several ingredients are separately prepared and are mixed in the following order and proportions:

One hundred pounds of peanut meal is first mixed in two-hundred o woun rodand-ninety pounds of water; then a solution composed of three poun s of commercial borax dissolved in from six to nine pounds 0 water is mixed therewith; two pounds of caustic sod is dissolved in four to six poun s of wa er and mixed therewith; one and a-half pounds of ermanan of oash is dissolved in thre o epo'u'ns of ounds of h drated lime is mixed with thirty to for your poun slot water and added to the mixture; and a solution of eight pounds of co er sul hate in sixteen to twenty-three pounds of water is mixed with the mass. The whole trams thoroughly mixed and is then ready for use. It should have the consistency of a heavy liquid, such as molasses. The quantity of water used in the preparation may be about two and three-quarter times the quantity of dry ingredients. The water aids in bringing the mixture into a homogeneous mass and controls its fluidity.

When a cheaper glue is desired a filler cium c n; and fifty pounds of sodium 51 1c e isso ved in water may be a e This prepartion needs no warming or cooking to make it ready for use and can be applied at any time within twenty-four hours after the mixture has been prepared. The peanut meal used in this glue is the ordinary commercial product and contains a'small amount of oil. The potassium permanganate is an oxidizin a ent to act on the 0113 or fats to prevenE tlielr saponlfication when coming in contact with alkalies or caustics. The hydrated lime is used to assist in shortening the time that it takes the glue to set. The copper sulphate acts as I ent. The sodium silicate y a -ii er u exercises a certain amount of action on the protein, as is well known in the glue manufacturing trade. The calcium chloride is adapted to release the soda from the silicate and to prevent so teen parts of hydrated lime and eight parts 9 of copper sulphate each separately dissolved or mixed with water and separately mixed with the mass.

3. A fluid composition adapted to form a water resistant, strong, non-abrasive glue comprising peanut meal, borax, caustic soda, permanganate of potash, hydrated lime,

comprisinga mixture of three pounds of calcopper sulphate, calcium chloride, and sodium silicate, mixed in water.

4. A fluid composition adapted to form a Water resistant, strong, non-abrasive glue 5 comprising a mixture of about one hundred parts of peanut meal, three parts of commercial bor'ax, two parts caustic soda, one

and a-half parts of ermanganate ofpotash, fifteen parts of hydrated lime, eight parts of copper sulphate, three parts of calciu chloride and fifty parts of sodium sTlTc a't each separately" dissolved ormixed' with Water and separately mixed with the mass.
